<gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15785619571331668830389">Porphyrin</gwmw> derivatives are promising organic semiconductor materials. The aggregation structure can be controlled by changing the functional groups and the central metal atom. The present study reveals that a highly ordered <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15785619597593499168649">polycrystalline</gwmw> thin film of <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15785619597596787441581">porphyrin</gwmw> derivative is readily obtained at room temperature by using the C–H/N <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15785619597590402902355">intermolecular</gwmw> interaction between the porphyrin ring and the <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15785619597599845813939">pyridyl</gwmw> rings of the functional groups. This <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15785619607548751227881">intermolecular</gwmw> interaction is formed when the <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15785619607546186738860">porphyrin</gwmw> rings can be distorted.
